[issue17985] multiprocessing Queue.qsize() and Queue.empty() with different results

[Richard Oudkerk]

Richard Oudkerk added the comment:

>From the docs:

 qsize()
    Return the approximate size of the queue. Because of
    multithreading/multiprocessing semantics, this number
    is not reliable.

Adding a short sleep before calling qsize() and empty() should make things appear to work.

But really, there are no good reasons for using qsize() except for debugging.  The same applies to queue.Queue.
